Bear in mind that many commercial ranges now ban TulAmmo due to that issue. It doesn't do to have cheap ammunition if there's nowhere to shoot it.I notice i get a lot of sparks and hot embers flying down range though.
Count me among that number. I've seen it with two AR-15's. While the problem might be a bit over-stated, it's still a possibility.Steel cartridge cases are believed by some to cause premature failures including extractor breakage.
